Loosing backward compability is what i'm most concerned about. For example i have many important documents created with MS Word 2.0, and Word 97 cannot even open them! (I don't have or use Word 97 myself, or any other version than 2.0, but i tryed it on a friends computer.) Oh well, StarOffice 5.2 does at least open them, formatting is not perfect, but it _does_ at least try... (I use OpenOffice for my work documents from now on, both on Linux and on Windows.) Another example: Why did AutoCAD dump the command dbtrans from their newer versions of AutoCAD? Now i cannot any longer automatically correct the text in older DOS (AutoCAD R12) drawings. DWF isn't an option: What the #@%%!!!, i want access to _my_ data! Even if it's old! Consider this scenario: I create a drawing of some construction. Ten years later the customer want to change something on that construction, and of course i try to open the old drawing file, and change what need to be changed in the file, instead of drawing everything again from scratch. Too bad, AutoDesk decided that i don't need the ability to open my old files any longer, so they removed that ability from the CAD program i use by then... DWF doesn't help at all then. Tomas
